LAMP HOLDER FOR IKINER3 CAPS.

Application filed July 25, 1924. Serial No. 728,222.

To all whom it may concern:

Be it known that I, Josnrn Basra, a citizen of the United States, andresident of Martins Ferry, in the county of Belmont and State of Ohio,have invented certain new and useful Improvements in Lamp Holders forMiners Caps, of which the following isa specification.

My invention is in the nature of an improvement upon the constructiondisclosed in my prior Patent No. 1,397,200 of November 15, 1921., and isintended to overcome certain min-or objections to the patented deviceand to improve the same in the light of experience.

An object of-the invention is to provide a holder that may be employedwith a cap carried frame of somewhat flexible material and willstrengthen and support the same in proper form.

Another object is to provide a holder into which the hook of the lampcan be readily inserted without taking care to have the lamp in anyparticular position, and wherein II the hook will be firmly supported atseveral points against any swinging movement either sidewise or fromfront to rear.

Other objects will be apparent from the following detailed descriptionand the appended claims.

In the drawings:

Figure 1 is a perspective View of a cap with the holder attached and thelamp re moved.

Figure 2 is a perspective view of the supporting frame to which theholder is at tached.

Figure 3 is a vertical section through a portion of the cap, the frameand the holder, with the lamp indicated in dotted outlines.

Figure 4 is a bottom plan view of the holder.

Figure 5 is a top plan view of the holder.

The drawings disclose the usual miners cap A to the front of which isfastened the Z-shaped frame B of leather or fibre or similar materialwhich bends with considerable ease. The upper arm 1 of the frame B isattached to the top of the cap and the lower arm 2 to the visor, Whilethe portion 3 occupies a substantially vertical position when the deviceis in use. The fastenings are preferably rivets or similar means.

If a holder such as shown in my prior patent is attached to a frame ofany material which may bend without difficulty, it is apt to distort theframe and allow the lamp to hang in irregular and varying positions. Ihave, therefore, devised my new and improved holder which forms mypresent invention and which cooperates especially with a frame 13 suchas described although so far as some features are concerned, it hasgreat utility when employed with other types of fran'ies.

This holder may be designated as a whole by the reference letter C andis made of copper, brass or other desired material. It has a top portionwhichrests on and is attached to the top portion 1 of the frame B and afront portion 5 at substantially right angles thereto which contactswith and is attached to the upperpart of the vertical portion 3 of theframe.

Closely adjacent the bond 6 between the portions 1 and 3 of the frame Bis a substantially circular hole 7 which communicates with a \l-shapedcut 8 extending downward into the vertical portion 3. The upper or topportion 4 of the holder has a depending tubular extension 9 whichextends through the hole 7 Communicating with the front side of the topof the extension 9 is a groove 10 in the top, front and through theright angle portion 11 of the holder. This groove extends downwardalmost to the bottom of the holder but is deepest at the right angle 11.It is not cut clear through the metal but the angle portion is thickenedso that the bottom 12 of this groove lies within the ll-shaped cut 8 inthe frame B, as clearly illustrated in Figure 3.

A flange 13 surrounds the top of the tubu lar extension 9 and the groove10 in the top part 4 of the holder. The top of the eX- tension 9 isflared outwardly at 15 and communicates with the groove in order toreceive readily the straight end of the hook d of the lamp D when it ispositioned. For a similar purpose the front inside corners of the flange13 are beveled at 14 as shown.

When the straight portion of the hookd is within the tubular extension9, obviously fore and aft swinging movement of the lamp is prevented,and since the curved portion d" of the hook lies in the groove 10 andcontacts with the bottom thereof through substantially its whole extent,any sidcwise movement is prevented, so that the lamp is held against anymovement independent of the cap.

The thickened angle portion 11 of the holder enables the groove 10 to bemade quite deep which aids in preventing any accidental displacement.The right angle form of the holder will prevent any bending of theZ-shaped frame B at its upper bend and will maintain this frame inproper form throughout a long period of use.

It is obvious that the lamp hook cl may be readily and quickly insertedin the holder and that the lamp will be held firmly against movementrelative to the cap. Various detail changes as regards material,proportions and the like may be made without departing from the spiritof the invention which is to be regarded as limited only by the scope ofthe appended claims.

I claim as my invention:

1. A device for supporting a miners lamp upon a cap comprising aZ-shaped frame of somewhat flexible material having an opening in thetop adjacent the upper bend communicating with a groove extending downin the vertical part, a right angle holder attached to said frame andhaving a tubular extension extending downward through said opening and agroove communicating therewith and extending downward in the frontportion of the holder and a flange at the sides of the groove on the topof the holder and having its inner front corners beveled.

2. A holder for miners lamps comprising a right angle metal memberthickened at the right angle, a downward tubular extension from the topof said member and a deep groove in the thickened portion communicatingwith said extension, whereby the strai ht portion of the lamp hook isreceived in the extension and the curved portion fits snugly in saidgroove substantially throughout its extent.

3. A holder for miners lamps comprising a right angle metal memberthickened at the right angle, and a downward tubular extension from thetop of said member and having a flared upper end, the thickened rightangle portion and the front having a groove which communicates with theextension and has flanges at the sides thereof on the top portion, whichflanges are beveled on their front inner corners, whereby the straightportion of the lamp hook is received in the extension and the curvedportion fits snugly in said groove substantially throughout its length.

In testimony whereof, I have hereunto subscribed my name.

JOSEPH BARTA.
